  Possible duplicate of https://forum.nim-lang.org/t/1067, however this is what I came up with:

  import unicode
  
  let s = "Привет!"
  echo s.runeStrAtPos(1)
  Run

  Which outputs "р" https://play.nim-lang.org/#ix=3BQU

  Warning: as stated in documentation, this proc may lead to performance issues, so someone might come up with a better and more efficient solution.

  Note the difference: runeAtPos returns a Rune (the Unicode equivalent of char), runeStrAtPos returns a string (like in Python).
